Abstract
A steerable rotatable member such as a pulley, sprocket or timing gear which can be mounted on a shaft so that the plane of the rotatable member may be positioned at selected angles other than a 90.degree. angle to the axis of rotation of the shaft. A torque transmitting member, commonly in the shape of a planar disc, is used to operatively connect the shaft and the rim of the rotatable member. The disc radially elongates and laterally flexes as the rotatable member rotates. A sleeve member may be used to connect the disc to the shaft. When used as a driver, a key may be used to transmit power from the shaft to the sleeve. The use of an elongated groove in the shaft permits the rotatable member to be adjustably moved to different locations along the axial length of the shaft.
