ABSTRACT:
A coupling mechanism includes a driven coupling for mating with a driving coupling. The driven coupling includes a cylinder flange, a concentric shaft that extends axially outwardly from the flange, and a cylindrical driven coupling member that extends axially outwardly from the concentric shaft. The driven coupling member includes a flexible membrane that encases non-rigid fill material, such as, e.g., a flowable granular material or a non-Newtonian fluid. The driven coupling member has a non-twisted, triangular cross-section, and is configured such that, when it is operationally engaged with the driving coupling, the non-rigid material substantially solidifies, thereby providing a substantially non-flexible structure for the membrane. The driven coupling may be connected to, for example, a photoreceptor drum of a material supply module, and the driving coupling may be connected to a reprographic device.
