A tool driver comprising a shaft, a shank, a flange, a clamp and a retainer. The shaft has a longitudinal axis and opposed ends. The shank is joined to one end of the shaft. The flange is joined to the other end of the shaft and has an outwardly facing flange surface extending from the shaft transversely of the axis. The clamp has a clamping surface facing the flange surface. The clamp is movable axially relative to the flange to vary the separation of the surfaces. The retainer is operatively connected to the clamp and is movable relative to the clamp between a first position and a second position. The retainer, in the first position, precludes relative movement of the clamp and the flange.
