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 shaft adapter, a collet, a ferrule, and a club head having an interior chamber. 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 adapter so as to allow adjustment of the shaft position with respect to the club head.

The kit of claim 1, further comprising information relating to a face angle, a lie angle, and a loft angle of the club head in relation to the different configurations of the collet in the interior chamber of the club head. 6. A kit comprising: a first golf club shaft having a first set of shaft performance characteristics;a collet having an inner periphery and an outer periphery;a first club head having an interior chamber configured to receive the collet, wherein the first club head has a first set of club head performance characteristics;a receiving mechanism configured to fit inside an interior chamber of the club head and configured to releasably receive and secure the collet;a first rotation inhibiting structure configured to fit inside an interior chamber of the club head and configured to mate with a second rotation inhibiting structure of the collet;a first shaft adapter configured to fit on an end of the first golf club shaft;wherein the first shaft adapter comprises an axial direction change region; wherein the inner periphery of the collet is configured to releasably receive the first shaft adapter and the outer periphery of the collet is configured to be releasably secured by the receiving mechanism of the club head; anda ferrule configured to releasably engage the collet and constrict the inner periphery of the collet to prevent rotational movement of the first shaft adapter with respect to the first club head. 7. The kit of claim 6, wherein the axial direction change region is configured to offset an axis of the first golf club shaft with respect to a hosel axis of the first golf club head about 2.5 degrees. 8. The kit of claim 6, further comprising: a second golf club shaft having a second set of shaft performance characteristics different from the first set of shaft performance characteristics; anda second shaft adapter configured to fit on an end of the second golf club shaft;wherein the second shaft adapter comprises an axial direction change region; andwherein the inner periphery of the collet is configured to releasably receive the second shaft adapter, and the ferrule constricts the inner periphery of the collet to prevent rotational movement of the second shaft adapter with respect to the first club head. 9. The kit of claim 8, wherein the shaft performance characteristics includes one or more of the following: a flex rating, a flex point, a kick point, a stiffness rating, or material composition. 10. The kit of claim 6, further comprising: a second club head having an interior chamber configured to receive the collet, wherein the second club head has a second set of club head performance characteristics different from the first set of club head performance characteristics. 11. The kit of claim 10, wherein the club head performance characteristics includes one or more of the following: a loft angle, a lie angle, a face angle, a set of offset features, or a set of weighting characteristics. 12. The kit of claim 10, further comprising: instructions for instructing a person to perform a method of: releasably inserting a collet into an interior chamber of a first golf club head, wherein the interior chamber houses a first rotation inhibiting structure that engages a second rotation inhibiting structure of the collet, preventing rotation of the collet within the first golf club head, wherein the collet is configured to be releasably received within the interior chamber of the first golf club head at a plurality of different configurations, wherein at least one configuration provides different club characteristics than another configuration;releasably inserting a first shaft adapter into the collet, wherein the first shaft adapter is configured to fit on an end of a first golf club shaft; andreleasably securing the ferrule to the collet, constricting the diameter of the collet to prevent rotational movement of the first shaft adapter into the first golf club head. 13. The kit of claim 12, wherein the instructions for instructing a person to perform a method further includes the steps of: removing the ferrule from the collet, thereby releasing the first shaft adapter and the first golf club shaft from the first golf club head;releasably inserting a second shaft adapter into the collet, wherein the second shaft adapter is configured to fit on an end of a second golf club shaft; andreleasably securing the ferrule to the collet, constricting the diameter of the collet to prevent rotational movement of the second shaft adapter with respect to the first golf club head. 14.
