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, comprising: a golf club head having a hosel area that provides access to a club head chamber defined in the club head;a shaft adapter being generally cylindrical in shape having a first end and an opposite second end, 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;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, wherein the second rotation-inhibiting structure is not uniform around the circumference of the internal bore on the first end of the hosel adapter, and further wherein an exterior surface of the hosel adapter includes a third rotation-inhibiting structure, and wherein the third rotation-inhibiting structure is not uniform around the circumference of the exterior surface of the hosel adapter;an internal bore located within the club head chamber, the internal bore includes a fourth rotation-inhibiting structure that engages the third rotation-inhibiting structure, wherein the fourth rotation-inhibiting structure is not uniform around the circumference of the internal bore;a shaft engaged in a cylindrical interior chamber of the shaft adapter; anda securing system for releasably securing the shaft adapter and the hosel adapter,wherein the adjustment of one of a face angle or a loft angle of the club head is based on a first indicator on the hosel adapter and the adjustment of the other of the face angle or the loft angle is set by aligning a second indicator on the shaft adapter to the first indicator, 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 of claim 1, wherein the first rotation-inhibiting structure includes a first spline configuration, the second rotation-inhibiting structure includes a second spline configuration, the third rotation-inhibiting structure includes a third spline configuration, and the fourth rotation-inhibiting structure includes a fourth spline configuration. 3. The golf club of claim 2, wherein the engagement of the first spline configuration and the second spline configuration limits the adjustability of the loft angle to five different loft angles. 4. The golf club of claim 3, wherein the five loft angles are 8.5 degrees, 9.5 degrees, 10.5 degrees, 11.5 degrees, and 12.5 degrees. 5. The golf club of claim 2, wherein the engagement of the third spline configuration and the fourth spline configuration limits the adjustability of the face angle to three different face angle configurations. 6. The golf club of claim 5, wherein the three face angle configurations are open, neutral, and closed. 7. A golf club having a releasably coupled head and shaft comprising: a connection mechanism to couple the head to the shaft, said connection mechanism including a hosel adapter insertable into a hosel of the head and rotatable inside the hosel between a first plurality of rotational positions, and a shaft adapter coupled to the shaft at a distal end, the shaft adapter configured to fit into the hosel adapter, said shaft adapter being rotatable inside said hosel adapter between a second plurality of rotational positions,wherein at least one of the hosel adapter or shaft adapter is releasably connected to either the shaft or the head, further wherein the first plurality of rotational positions changes a first angular relationship between the head and the shaft and the second plurality of rotational positions changes a second angular relationship between the head and the shaft, wherein the first angular relationship and the second angular relationship are adjusted effectively independent of each other, wherein the first and second angular relationships are a face angle of the head and a loft angle of the head,further wherein the first plurality of rotational positions is limited by a first spline configuration between the hosel adapter and the hosel of the head and the second plurality of rotational positions is limited by a second spline configuration between the hosel adapter and the shaft adapter,wherein the adjustment of one of a face angle or a loft angle of the head is based on a first indicator on the hosel adapter and the adjustment of the other of the face angle or the loft angle is set by aligning a second indicator on the shaft adapter to the first indicator, wherein the first spline configuration is defined by a first pair of non-uniform rotation-inhibiting structures between the hosel adapter and the hosel, and the second spline configuration is defined by a second pair of non-uniform rotation-inhibiting structures between the shaft adapter and the hosel adapter. 8. The golf club of claim 7, wherein the engagement of the first spline configuration limits the adjustability of the loft angle to five different loft angles. 9. The golf club of claim 8, wherein the five loft angles are 8.5 degrees, 9.5 degrees, 10.5 degrees, 11.5 degrees, and 12.5 degrees. 10. The golf club of claim 7, wherein the engagement of the second spline configuration limits the adjustability of the face angle to three different face angle configurations. 11. The golf club of claim 10, wherein the three face angle configurations are open, neutral, and closed. 12. A golf club having a releasably coupled head and shaft comprising: a connection mechanism to couple the head to the shaft, said connection mechanism including a hosel adapter insertable into a hosel of the head and rotatable inside the hosel between a first plurality of rotational positions associated with a loft angle of the head, and a shaft adapter coupled to the shaft at a distal end and insertable into the hosel adapter and rotatable inside said hosel adapter between a second plurality of rotational positions associated with a face angle of the head,wherein at least one of the hosel adapter or the shaft adapter is releasably connected to either the shaft or the head, further wherein the first plurality of rotational positions changes the loft angle of the head and the second plurality of rotational positions changes the face angle of the head and the shaft, wherein changing the face angle is effectively independent of changing the loft angle, and changing the loft angle is effectively independent of changing the face angle,further wherein the first plurality of rotational positions is limited by a first spline configuration between the hosel adapter and the hosel of the head and the second plurality of rotational positions is limited by a second spline configuration between the hosel adapter and the shaft adapter,wherein the adjustment of one of a face angle or a loft angle of the head is based on a first indicator on the hosel adapter and the adjustment of the other of the face angle or the loft angle is set by aligning a second indicator on the shaft adapter to the first indicator, and wherein the first spline configuration is defined by a first pair of non-uniform rotation-inhibiting structures between the hosel adapter and the hosel, and the second spline configuration is defined by a second pair of non-uniform rotation-inhibiting structures between the shaft adapter and the hosel adapter. 13. The golf club of claim 12, wherein the engagement of the first spline configuration limits the adjustability of the loft angle to five different loft angles. 14. The golf club of claim 13, wherein the five loft angles are 8.5 degrees, 9.5 degrees, 10.5 degrees, 11.5 degrees, and 12.5 degrees. 15. The golf club of claim 12, wherein the engagement of the second spline configuration limits the adjustability of the face angle to three different face angle configurations. 16. The golf club of claim 15, wherein the three face angle configurations are open, neutral, and closed.
