ABSTRACT:
A mounting nut for a viscous fluid coupling. The nut is axially movable upon the input shaft of the coupling into engagement with a contact surface on the flange of the input shaft. Threads are provided on the nut for engagement with threads on a flange secured to the mounting shaft. The flange on the input shaft and the flange on the mounting shaft each have a flat surface perpendicular to the axis of rotation of the coupling. When the nut is threaded onto the flange on the mounting shaft the two flat surfaces are drawn together and forced into tight mating engagement. A key may be provided between the two flanges to ensure 1:1 rotation between the coupling and the mounting shaft.
