Interchangeable shaft system
A golf club incorporating an interchangeable shaft system includes a shaft, a shaft sleeve, a club head. The shaft sleeve is coupled to an end of the shaft and is received in a hosel included in the club head. The shaft sleeve is removably coupled to the club head. Hosel and shaft sleeve alignment features provide discreet orientations between the shaft and club head.

a fastener that releasably couples the shaft sleeve to the club head,
wherein the hosel alignment features, sleeve alignment features and wedge alignment features comprise a plurality of complementary tangs and notches,
wherein the hosel alignment features each taper in a direction of a longitudinal axis of the hosel,
wherein the sleeve alignment features each taper in a direction of a longitudinal axis of the sleeve body,
wherein the wedge alignment features are tapered to complement the mating hosel and sleeve alignment features,
wherein at least one of the hosel, sleeve and wedge indicia qualitatively indicate the configuration of the golf club related to at least one of face angle, lie angle and loft angle, and
wherein the shaft sleeve defines a shaft bore that is angled relative to the sleeve body to provide a shaft angle between the shaft sleeve and the shaft.
10. The golf club of claim 9 , wherein the plurality of hosel alignment features are notches extending through only a portion of a side wall of the hosel so that they do not intersect an outer surface of the hosel.
11. The golf club of claim 9 , wherein the hosel alignment features are generally trapezoidal in a cross-section taken in a plane that is parallel to a longitudinal axis of the hosel.
12. The golf club of claim 11 , wherein the hosel alignment features taper so that they define a narrowest portion oriented toward a sole of the golf club head.
13. The golf club of claim 9 , wherein the sleeve alignment features are generally trapezoidal in a cross-section taken in a plane that is parallel to a longitudinal axis of the sleeve body.
