Golf club heads are releasably engaged with shafts so that the club heads and shafts can be readily interchanged and/or so that the shaft position with respect to the club head can be readily changed. Assemblies for connecting the club head and shaft may include: (a) a shaft engaging member including a rotation-inhibiting structure; (b) a club head engaging member including a shaft-receiving chamber and a retaining structure for engaging the rotation-inhibiting structure; and (c) a securing system for releasably securing the shaft engaging member with respect to the club head engaging member. The club head and shaft may be changed by releasing the securing system and exchanging the original parts with different parts. Furthermore, the shaft may be bent or otherwise extend at an angle from the shaft engaging member so as to allow adjustment of the shaft position with respect to the club head.

A golf club according to claim 6, wherein the second end of the club head engaging member includes a portion extending beyond the rotation-inhibiting structure of the club head engaging member, wherein the second end of the shaft engaging member includes a projection extending beyond the rotation-inhibiting structure of the shaft engaging member, and wherein the projection extends into the portion of the club head engaging member extending beyond the rotation-inhibiting structure of the club head engaging member. 8. A golf club according to claim 7, further comprising: a retaining element extending into the portion of the club head engaging member extending beyond the rotation-inhibiting structure of the club head engaging member. 9. A golf club according to claim 7, further comprising: a retaining element engaged with the projection. 10. A golf club according to claim 6, further comprising: a retaining element extending into an opening provided at the second end of the club head engaging member. 11. A golf club according to claim 6, further comprising: a retaining element engaged with the second end of the club head engaging member. 12. A golf club according to claim 6, further comprising: a retaining element engaged with the second end of the shaft engaging member. 13. A golf club according to claim 6, wherein the rotation-inhibiting structure of the shaft engaging member extends less than 15% of an overall axial length of the shaft engaging member. 14. A method of assembling a golf club, comprising: engaging a shaft with a shaft engaging member having an exterior surface and an open first end that define a cylindrical interior chamber for receiving the shaft, wherein the exterior surface of the first end includes an extending portion extending in a radial direction away from the cylindrical interior chamber, wherein the exterior surface of the second end includes a rotation-inhibiting structure, the rotation-inhibiting structure located longitudinally entirely beyond the cylindrical interior chamber, and wherein the exterior surface extends in a first axial direction and the interior chamber extends in a second axial direction that differs from the first axial direction; engaging a golf club head with a club head engaging member having a first end and a second end, wherein the first end of the club head engaging member includes an opening, wherein the first end of the club head engaging member further includes a securing structure, and wherein an interior of the second end of the club head engaging member includes a rotation-inhibiting structure; engaging the shaft engaging member with the club head engaging member by inserting at least a portion of the shaft engaging member through the opening at the first end of the club head engaging member and by engaging the rotation-inhibiting structure of the shaft engaging member with the rotation-inhibiting structure of the club head engaging member; and releasably securing a securing member over the extending portion of the shaft engaging member with the securing structure of the club head engaging member, wherein the securing member, at least in part, releasably secures the shaft engaging member with the club head engaging member. 15.
