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. Golf clubs are provided that have spherical releasable connections between the golf club head and the golf club shaft along with head/shaft position adjusting features to allow interchange of shafts and heads and to allow modification of the head/shaft positioning properties. Assemblies for connecting the club head and shaft may include: a shaft adapter, a shaft retainer, and a hosel insert located within an interior chamber of the club head. The club head and shaft may be changed by releasing the securing system and exchanging the original parts with different parts. Furthermore, the shaft adapter may be rotated within the hosel insert to create different angles from the shaft so as to allow adjustment of the shaft position with respect to the club head.

1. A golf club, comprising: a golf club shaft;a golf club head having an interior chamber;a shaft retainer configured to be engaged with the golf club shaft;a hosel insert configured to releasably receive and secure the shaft retainer, the hosel insert located at least partially within the interior chamber and having an outer perimeter and an inner perimeter, wherein the outer perimeter is configured to be engaged with the interior chamber and the inner perimeter includes a rotation inhibiting structure; anda shaft adapter having an upper end and a lower end, wherein the upper end is attached to the golf club shaft and the lower end has a spherical member configured to mate with at least a portion of the rotation inhibiting structure to prevent rotation of the shaft adapter in relation to the club head, wherein the shaft adapter is configured to be inserted into the hosel insert at a plurality of different configurations, wherein a first configuration provides different club characteristics than a second configuration,wherein the spherical member includes a tab and the rotation inhibiting structure includes at least one receiving slot located within the inner perimeter of the hosel insert, the at least one receiving slot configured to receive the tab. 2. The golf club of claim 1, wherein the shaft adapter comprises an axial direction change region configured to offset an axis of the shaft with respect to a hosel axis of the golf club head. 3. The golf club of claim 2, wherein the offset is about 2.5 degrees. 4. The golf club of claim 1, wherein the shaft retainer includes threaded structures and the hosel insert comprises threaded securing structures configured to threadingly engage the threaded structures. 5. The golf club of claim 4, wherein the threaded structures of the shaft retainer are located on the exterior of the shaft retainer and the threaded securing structures of the hosel insert are on the inner perimeter of the hosel insert. 6. The golf club of claim 1, wherein the shaft retainer further comprises a gripping structure configured to aid a user in connecting the shaft retainer to and disconnecting the shaft retainer from the hosel insert. 7. The golf club of claim 1, wherein when the shaft adapter is in the first configuration, the tab is configured to be inserted into a first receiving slot. 8. The golf club of claim 7, wherein when the shaft adapter is in the second configuration, the tab is configured to be inserted into a second receiving slot and a second facet mates with the mating face, and wherein in the first configuration the spherical member is in a different rotational position within the hosel insert than in the second configuration. 9. A connection assembly for releasably connecting a golf club shaft and golf club head comprising: a shaft retainer configured to be engaged with a golf club shaft;a hosel insert configured to releasably receive and secure the shaft retainer, the hosel insert having an outer perimeter and an inner perimeter, wherein the outer perimeter is configured to be engaged with a golf club head and the inner perimeter includes a rotation inhibiting structure; anda shaft adapter having an upper end and a lower end, wherein the lower end has a spherical member configured to mate with at least a portion of the rotation inhibiting structure to prevent rotation of the shaft adapter in relation to the club head, wherein the shaft adapter is configured to be inserted into the hosel insert at a plurality of different configurations, wherein a first configuration provides different club characteristics than a second configuration,wherein the spherical member includes a tab and the rotation inhibiting structure includes at least one receiving slot located within the inner perimeter of the hosel insert and the at least one receiving slot is configured to receive the tab. 10. The connection assembly of claim 9, wherein the shaft adapter comprises an axial direction change region configured to offset an axis of the shaft with respect to a hosel axis of the golf club head. 11. The connection assembly of claim 10, wherein the offset is about 2.5 degrees. 12. The connection assembly of claim 9, wherein the shaft retainer includes threaded structures and the hosel insert comprises threaded securing structures configured to threadingly engage the threaded structures. 13. The connection assembly of claim 12, wherein the threaded structures of the shaft retainer are located on the exterior of the shaft retainer and the threaded securing structures of the hosel insert are on the inner perimeter of the hosel insert. 14. The connection assembly of claim 9, wherein the shaft retainer further comprises a gripping structure configured to aid a user in connecting the shaft retainer to and disconnecting the shaft retainer from the hosel insert. 15. The connection assembly of claim 9, wherein when the shaft adapter is in the first configuration, the tab is configured to be inserted into a first receiving slot. 16. The connection assembly of claim 15, wherein when the shaft adapter is in the second configuration, the tab is configured to be inserted into a second receiving slot, and wherein in the first configuration the spherical member is in a different rotational position within the hosel insert than in the second configuration.
