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.
