Abstract
An interface drive coupler for a replaceable unit of an electrophotographic image forming device according to one example embodiment includes a first component and a second component coaxial with the first component along a rotational axis of the interface drive coupler. A force receiving portion is positioned on the first component and a force transmitting portion is positioned on the second component. One of the first component and the second component includes a male connector and the other of the first component and the second component includes a female connector that matably receives the male connector. Each of the male connector and the female connector includes a helical thread that extends circumferentially around the rotational axis of the interface drive coupler and that is angled in an operative rotational direction of the interface drive coupler in a direction from the force receiving portion toward the force transmitting portion.
