Golf club heads are releasably engaged with shafts so they may be readily interchanged and/or so that the shaft orientation with respect to the club head can be readily changed. Assemblies for connecting the club head and shaft may include a shaft adapter and a head adapter. The shaft adapter may have an exterior surface extending along a first axis and a bore having a cross-sectional shape along a second axis configured to attach to a shaft member. The second end of the shaft adapter has a cross-sectional shape of a regular polygon. The head adapter has a first end and a second end along a first axis and a bore having a shape of a regular polygon along a second axis that is shaped to receive the second end of the shaft adapter in a plurality of orientations.
