Abstract
A system for transferring torque with zero lash from a driver to a driven object is provided. The system includes a shaft disposed about a rotational axis and a hub defining a bore that receives the shaft. The shaft and hub are each configured for coupling to one of the driver and driven object. The shaft defines a flat on a radially outer surface and the hub defines a flat on a radially inner surface opposing the flat in the shaft. In one embodiment, the shaft includes a threaded bore and the hub includes an aligned through bore. Rotation of a threaded fastener in the bores draws the flat into engagement. In another embodiment, the hub includes a threaded through bore. Rotation of a fastener extending through the bore and engaging the shaft diametrically opposite the flats urges the flats into engagement.
