A temporary shaft-component connection for assembling a selected golf club shaft with a club head and/or hand grip segment, to facilitate custom club design and fitting to suit the needs and preferences of an individual golfer. The temporary shaft-component connection is particularly designed for use with nonmetallic club shafts formed from a graphite-based composite material or the like having a range of different lengths and stiffness (whip) characteristics. In a shaft-head connection, a metal adapter insert is mounted onto a lower end of the club shaft and includes one or more flat surfaces for reception into a matingly shaped socket in the hosel of a selected club head to prevent relative rotation between the club shaft and head. A compression nut carried on the shaft is threaded onto the hosel to axially engage and retain a thrust flange on the shaft or adapter or adapter insert, to prevent axial separation of the club head and shaft.

The invention claimed is: 1. An adapter for connecting a golf club shaft with a golf club head, the adapter comprising: a body member including a first end and a second end opposite the first end, wherein the first end defines an opening for receiving a golf club shaft and the second end defines an exterior surface having plural rotation-inhibiting sides; a thrust flange provided along the body member between the first end and the second end; a connection means for connecting the body member with a golf club head, wherein the connection means includes a partially closed first end through which the first end of the body member extends, the partially closed first end further defining a thrust shoulder for engaging the thrust flange, and wherein the connection means further includes a second end opposite the partially closed first end, the second end extending over at least a portion of the rotation-inhibiting sides of the body member; and an adapter socket for fixedly engaging with a golf club head, wherein the adapter socket includes a first end and a second end opposite the first end, wherein the first end of the adapter socket defines an opening for releasably receiving and engaging the exterior surface of the second end of the body member in a non-rotatable manner and the second end of the adapter socket includes exterior surfaces for fixedly engaging within a hosel portion of the golf club head wherein said shaft is able to extend within said hosel portion. 2. An adapter according to claim 1, wherein the thrust flange is integrally formed as part of the body member. 3. An adapter according to claim 1, wherein the first end of the adapter socket includes structures that engage the connection means. 4. An adapter according to claim 3, wherein the connection means includes internal threads that engage external threads provided on the adapter socket. 5. An adapter according to claim 1, wherein the engagement between the opening of the adapter socket and the exterior surface of the second end of the body member is configured to prevent rotation between the shaft and the golf club head. 6. An adapter according to claim 1, wherein the rotation-inhibiting sides of the exterior surface of the body member include plural flat sides. 7. A golf club, comprising: a club head; a shaft; and an adapter for releasably connecting the club head with the shaft, wherein the adapter includes: a body member having a first end and a second end opposite the first end, wherein the first end defines an opening into which the shaft is fixedly engaged, and wherein the second end defines an exterior surface having plural rotation-inhibiting sides; a thrust flange provided along the body member between the first end and the second end; a connection means for releasably connecting the body member with the club head, wherein the connection means includes a partially closed first end through which the first end of the body member extends, the partially closed first end further defining a thrust shoulder for engaging the thrust flange, and wherein the connection means further includes a second end opposite the partially closed first end, the second end of the connection means releasably engaging the club head; and an adapter socket fixedly engaged with the club head, wherein the adapter socket includes a first end and a second end opposite the first end, wherein the first end of the adapter socket defines an opening for releasably receiving and engaging the exterior surface of the second end of the body member in a non-rotatable manner and the second end of the adapter socket includes exterior surfaces that fixedly engage a hosel portion of the club head wherein said shaft is able to extend within said hosel portion. 8. A golf club according to claim 7, wherein the thrust flange is integrally formed as part of the body member. 9. A golf club according to claim 7, wherein the exterior surface of the adapter socket includes structures for releasably engaging the connection means. 10. A golf club according to claim 7, wherein the exterior surface of the adapter socket includes threads for engaging threads provided at the second end of the connection means. 11. A golf club according to claim 7, wherein the adapter socket includes interior surfaces that engage the exterior surface of the second end of the body member in a non-rotatable manner. 12. A golf club according to claim 7, wherein the connection means includes a compression nut, wherein the connection between the compression nut and the first end of the adapter socket is configured to retain the thrust flange and prevent axial separation of the shaft and club head. 13. A golf club according to claim 7, wherein the rotation-inhibiting sides of the body member include plural flat sides. 14. A golf club according to claim 7, wherein the club head is a wood-type golf club head. 15. A golf club, comprising: a club head having a hosel, with a round bore in the hosel; a shaft; and an adapter for releasably connecting the club head with the shaft, wherein the adapter includes: an adapter socket having a round exterior surface portion that engages the club head bore, threads at its free end, and flat interior surfaces, wherein an upper portion of the adapter socket overlies the hosel, a body member having a first end and a second end, further having flat sides at the first end to match the flat interior surfaces of the adapter socket and a shaft receiving opening on the second end, wherein the flat sides of the first end engage the flat interior surfaces of the adapter socket to prevent rotation between the shaft and the club head wherein said shaft is able to extend within said hosel, a thrust flange provided along the body member between the first end and the second end, and a connection element for releasably connecting the body member with the club head, wherein the connection element includes a partially closed first end through which the first end of the body member extends, the partially closed first end further defining a thrust shoulder for engaging the thrust flange, and wherein the connection element further includes a second end opposite the partially closed first end, the second end of the connection element having interior threads engaging the exterior threads on the adapter socket, thereby releasably engaging the club head and the shaft together, wherein the connection between the connection element and the adapter socket is configured to prevent axial separation of the shaft and club head.
