at least one actuatable reaction member comprising a threaded rod that is threadingly coupled to the connector body, wherein, when actuated, an inner surface of the at least one actuatable reaction member is adapted to be urged radially along a line of travel that is axially spaced apart from a sealing interface between the first and second hubs and into direct abutting contact with an outer surface of the first hub.
2 . The connector of claim 1 , wherein the inner surface of the at least one actuatable reaction member is an end surface of the threaded rod.
3 . The connector of claim 1 , wherein the at least one actuatable reaction member comprises a plurality of actuatable reaction members.
4 . The connector of claim 1 , wherein the at least one actuatable reaction member further comprises a partial-ring structure that is rotatably coupled to the threaded rod, the inner surface of the at least one actuatable reaction member being an inner surface of the partial-ring structure.
5 . The connector of claim 4 , wherein the partial-ring structure is rotatably coupled to the threaded rod with a ball and socket joint.
6 . The connector of claim 4 , wherein the inner surface of the partial-ring structure has a radius of curvature that is substantially the same as a radius of curvature of the outer surface of the first hub.
7 . The connector of claim 4 , wherein the at least one actuatable reaction member comprises a plurality of actuatable reaction members.
8 . The connector of claim 4 , wherein at least a portion of the at least one actuatable reaction member is positioned in a recess formed in the body.
9 . The connector of claim 4 , wherein the threaded rod is a first threaded rod, the at least one actuatable reaction member further comprising a second threaded rod that is rotatably coupled to the partial-ring structure.
10 . The connector of claim 9 , wherein the at least one actuatable reaction member further comprises at least one third threaded rod that is rotatably coupled to the partial-ring structure.
11 . The connector of claim 10 , wherein the partial-ring structure is a C-shaped ring structure.
12 . The connector of claim 1 , wherein the first hub comprises a wellhead and the second hub comprises a riser.
13 . The connector of claim 1 , wherein, when actuated, the inner surface of the at least one actuatable reaction member is further adapted to be urged radially into an operating position wherein the inner surface is positioned adjacent to but does not contact the outer surface of the first hub.
14 . A connector that is adapted to establish a sealed connection between first and second hubs, the connector comprising:
a body that is adapted to be positioned adjacent to the first and second hubs;
primary locking means for connecting the first hub to the second hub; and
