A releasable connection system for assembling a shaft and a club head, e.g., a golf club shaft and a golf club head. The connection system provides interchangeability between a shaft and a club head and allows the head to be adjusted with respect to the shaft. The mating structures between the shaft and the club head may be indexed for reproducible placement. In an embodiment, the connection system also includes retaining structures that maintain the connection fastener position when the head and shaft are separated.

1. A system for reversibly joining a club shaft to a club head, comprising: a fastener comprising a proximal end defining a head, a distal end defining a threaded portion, and a retaining shoulder positioned along a length of the fastener between and separate from the head and the threaded portion;a
1. A system for reversibly joining a club shaft to a club head, comprising: a fastener comprising a proximal end defining a head, a distal end defining a threaded portion, and a retaining shoulder positioned along a length of the fastener between and separate from the head and the threaded portion;a club head comprising a first opening, a second opening, and a retaining member positioned within an interior of the club head and axially aligned with the first opening, wherein the first opening and the retaining member are each configured to receive at least the distal end and the retaining shoulder of the fastener entirely therethrough, wherein the retaining member is configured to span a length of the fastener between the head and the retaining shoulder and to be in contact with the retaining shoulder to prevent movement of the fastener in a direction towards the first opening, wherein the retaining member is configured to retain the fastener within the interior of the club head and in axial alignment with the second opening of the club head; anda club shaft configured to be received through the second opening of the club head and reversibly receive at least the distal end of the fastener, thereby joining the shaft and the club head. 2. The system of claim 1, wherein the retaining member retains the fastener substantially centered in a socket that receives an end of the club shaft. 3. The system of claim 1, wherein the retaining member is constructed from a resilient material that allows the fastener shoulder to pass through the retaining member but prevents the head of the fastener to pass therethrough. 4. The system of claim 3, wherein the retaining member is a sleeve having slots spanning a portion of the retaining member. 5. The system of claim 4, wherein the sleeve is constructed from plastic or metal. 6. The system of claim 5, wherein the sleeve comprises protrusions that retain the sleeve in a hole in the club head. 7. The system of claim 3, wherein the retaining member is a clip having first protrusions that retain the retaining shoulder and second protrusions that retain the clip in a hole in the club head. 8. The system of claim 7, wherein the clip is constructed from plastic or metal. 9. The system of claim 1, wherein the fastener is a screw or bolt. 10. The system of claim 9, wherein the head of the screw or bolt is configured to receive a tool. 11. The system of claim 10, wherein the tool has a triangular, square, pentagonal, hexagonal, heptagonal, octagonal, cross, slot, or star shape. 12. The system of claim 9, wherein an end of the shaft comprises a threaded hole for receiving the screw or bolt. 13. The system of claim 1, wherein the retaining shoulder is tapered. 14. The system of claim 1, wherein the club head is a golf club head and the club shaft is a golf club shaft. 15. The system of claim 14, wherein the golf club head comprises a hosel and an end of the golf club shaft fits inside the hosel. 16. The system of claim 14, wherein the golf club head is a driver-type golf club head, a hybrid-type golf club head, an iron-type golf club head, or a putter. 17. The system of claim 14, wherein the golf club shaft is constructed from wood, metal, or a composite. 18. The golf club head of claim 1, wherein the retaining member comprises: a proximal end positioned adjacent to the first opening and configured to be in direct contact with the head of the fastener; anda distal end positioned within the interior of the club head and adjacent to the distal end of the fastener and configured to be in contact with the retaining shoulder of the fastener. 19. The golf club head of claim 1, wherein the retaining member spans the entire length of the fastener between the head and the retaining shoulder.
