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.

1. A golf club head/shaft connection assembly, comprising: a shaft adapter being generally cylindrical in shape having a first end and an opposite second end, wherein the first end includes a first opening providing access to a cylindrical interior chamber for receiving a golf club shaft, wherein an exterior surface of the shaft adapter includes a first rotation-inhibiting structure, wherein the first rotation-inhibiting structure is not uniform around the circumference of the exterior surface of the shaft adapter, and wherein the second end includes a securing structure and a stop ring extending radially from the second end of the shaft adapter;a hosel adapter being generally cylindrical in shape, wherein an internal bore on a first end of the hosel adapter includes a second rotation-inhibiting structure that engages the first rotation-inhibiting structure and a second end of the hosel adapter includes a first opening for receiving a securing member, wherein the second rotation-inhibiting structure is not uniform around the circumference of the internal bore of the hosel adapter, and further wherein an exterior surface of the hosel adapter includes a third rotation-inhibiting structure, wherein the third rotation-inhibiting structure is not uniform around the circumference of the exterior surface of the hosel adapter, wherein the stop ring maintains the continual engagement of the hosel adapter with the shaft adapter, wherein the third rotation-inhibiting structure engages a fourth rotation-inhibiting structure within an internal bore of a hosel of a club head, wherein the fourth rotation-inhibiting structure is not uniform around the circumference of the internal bore of the hosel; anda securing system for releasably engaging the securing structure,wherein the engagement between the first rotation-inhibiting structure and the second rotation-inhibiting structure limits the adjustment of one of a face angle or a loft angle of the club head and the engagement between the third rotation-inhibiting structure and the fourth rotation-inhibiting structure limits the adjustment of the other of the face angle or the loft angle of the club head, and adjusting the face angle is effectively independent of the adjustment of the loft angle, and adjusting the loft angle is effectively independent of the adjustment of the face angle. 2. The golf club head/shaft connection assembly of 1, wherein the stop ring is a compression o-ring located in a channel that extends radially around the second end of the shaft adapter. 3. The golf club of claim 1, the securing system further including a screw retention device that is sized such that the screw retention device retains the securing member in the club head when the securing member is disengaged from the shaft adapter. 4. The golf club of claim 1, wherein the engagement of a first spline configuration and a second spline configuration limits the adjustability of the loft angle to five different loft angles. 5. The golf club of claim 4, wherein the five loft angles are 8.5 degrees, 9.5 degrees, 10.5 degrees, 11.5 degrees, and 12.5 degrees. 6. The golf club of claim 1, wherein the engagement of a third spline configuration and a fourth spline configuration limits the adjustability of the face angle to three different face angle configurations. 7. The golf club of claim 6, wherein the three face angle configurations are open, neutral, and closed. 8. A golf club, comprising: a golf club head having a hosel area that provides access to a club head chamber defined in the club head, wherein the club head chamber extends completely through the club head and includes a first opening for receiving a securing member;a shaft adapter being generally cylindrical in shape having a first end and an opposite second end, wherein the first end includes a second opening providing access to a cylindrical interior chamber, wherein an exterior surface of the shaft adapter includes a first rotation-inhibiting structure, wherein the first rotation-inhibiting structure is not uniform around the circumference of the exterior surface of the shaft adapter, and wherein the second end includes a securing structure and a stop ring extending radially from the second end of the shaft adapter;a hosel adapter being generally cylindrical in shape, wherein an internal bore on a first end of the hosel adapter includes a second rotation-inhibiting structure that engages the first rotation-inhibiting structure and a second end of the hosel adapter includes a first opening for receiving a securing member, wherein the second rotation-inhibiting structure is not uniform around the circumference of the internal bore of the hosel adapter, and further wherein an exterior surface of the hosel adapter includes a third rotation-inhibiting structure, wherein the third rotation-inhibiting structure is not uniform around the circumference of the exterior surface of the hosel adapter, wherein the stop ring maintains the continual engagement of the hosel adapter with the shaft adapter, wherein the third rotation-inhibiting structure engages a fourth rotation-inhibiting structure within an internal bore of the hosel area of the golf club head, wherein the fourth rotation-inhibiting structure is not uniform around the circumference of the internal bore of the hosel area;a shaft engaged in the cylindrical interior chamber of the shaft adapter; anda securing system for releasably engaging the securing structure,wherein the engagement between the first rotation-inhibiting structure and the second rotation-inhibiting structure limits the adjustment of one of a face angle or a loft angle of the club head and the engagement between the third rotation-inhibiting structure and the fourth rotation-inhibiting structure limits the adjustment of the other of the face angle or the loft angle of the club head, and adjusting the face angle is effectively independent of the adjustment of the loft angle, and adjusting the loft angle is effectively independent of the adjustment of the face angle. 9. The golf club of claim 8, wherein the stop ring is a compression o-ring located in a channel that extends radially around the second end of the shaft adapter. 10. The golf club of claim 8, the securing system further including a screw retention device that is sized such that the screw retention device retains the securing member in the club head when the securing member is disengaged from the shaft adapter. 11. The golf club of claim 8, wherein the engagement of a first spline configuration and a second spline configuration limits the adjustability of the loft angle to five different loft angles. 12. The golf club of claim 11, wherein the five loft angles are 8.5 degrees, 9.5 degrees, 10.5 degrees, 11.5 degrees, and 12.5 degrees. 13. The golf club of claim 8, wherein the engagement of a third spline configuration and a fourth spline configuration limits the adjustability of the face angle to three different face angle configurations. 14. The golf club of claim 13, wherein the three face angle configurations are open, neutral, and closed.
