1. A golf club, comprising:
a golf club head including a hosel that defines a hosel bore;
an elongate shaft;
a shaft sleeve assembly including a sleeve body, a shaft adapter rotatably coupled to the sleeve body and fixedly coupled to a distal end portion of the shaft, and a locking member that locks the orientation of the shaft adapter relative to the sleeve body;
a fastener that releasably couples the sleeve body to the club head at least partially within the hosel bore, and
a wedge member disposed on the sleeve body and interposed between the sleeve body and the hosel, wherein the wedge member provides a wedge angle between the sleeve body and the hosel.
2. The golf club of claim 1 , wherein the shaft adapter comprises a shaft attachment portion and a projection portion, wherein the sleeve body includes a bore that receives the projection portion.
3. The golf club of claim 2 , wherein the locking member is coupled to the projection portion and interposed between the sleeve body and the shaft adapter.
4. The golf club of claim 2 , wherein the bore of the sleeve body is threaded and the projection portion is threaded.
5. The golf club of claim 4 , wherein the locking member is a threaded nut that is received on the threaded projection and interposed between the sleeve body and the shaft adapter.
6. The golf club of claim 1 , wherein the wedge member comprises wedge alignment features and the sleeve body comprises sleeve alignment features that engage the wedge alignment features.
7. The golf club of claim 1 , further comprising a retainer coupled to the sleeve body, wherein the retainer extends away from an outer surface of the sleeve body, wherein the wedge member is interposed between a portion of the sleeve body and the retainer so that the wedge member is retained on the sleeve body when the shaft sleeve assembly is separate from the golf club head.
8. The golf club of claim 1 , wherein at least a portion of the shaft adapter is angled relative to the sleeve body so that the shaft is angled relative to the sleeve body by a shaft angle.
9. The golf club of claim 8 , wherein the magnitude of the shaft angle is different than the magnitude of the wedge angle.
10. A golf club shaft sleeve assembly for attaching a golf club shaft to a golf club head, comprising:
a sleeve body,
a shaft adapter including a shaft attachment portion configured to be fixedly coupled to a distal end portion of a golf club shaft, wherein the shaft adapter is rotatably coupled to the sleeve body,
a locking member that locks the orientation of the shaft adapter relative to the sleeve body,
a wedge member disposed on the sleeve body, and
a retainer that is coupled to the sleeve body, wherein the retainer extends away from an outer surface of the sleeve body, wherein the wedge member is interposed between a portion of the sleeve body and the retainer so that the wedge member is retained on the sleeve body when the shaft sleeve assembly is separate from a golf club head.
11. The golf club shaft sleeve assembly of claim 10 , wherein the retainer is threaded onto the sleeve body.
12. The golf club shaft sleeve assembly of claim 10 , wherein the sleeve body comprises sleeve alignment features and the wedge comprises wedge alignment features, wherein the sleeve alignment features complement the wedge alignment features.
13. The golf club shaft sleeve assembly of claim 10 , wherein the shaft adapter comprises a shaft attachment portion and a projection portion, wherein the sleeve body includes a bore that receives the projection portion.
14. The golf club shaft sleeve assembly of claim 13 , wherein the locking member is coupled to the projection portion and interposed between the sleeve body and the shaft attachment portion.
15. The golf club shaft sleeve assembly of claim 13 , wherein the bore of the sleeve body is threaded and the projection portion is threaded.
16. The golf club shaft sleeve assembly of claim 15 , wherein the locking member is threaded onto the projection portion.
