Claim:
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; and a securing system for releasably engaging the securing structure, wherein the adjustment of one of a face angle or a loft angle of a 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.
