A magneto-rheological coupling (MRC) having an input assembly and an output member. The output member includes a generally cylindrical drum portion and a hub portion extending radially inwardly therefrom. The generally cylindrical drum portion has a low magnetically permeable region having a plurality of passages defined therein. Additionally, a plurality of apertures are defined by the hub portion. The plurality of passages and apertures enhance the flow of magneto-rheological fluid (MRF) within the MRC. The drum portion has a surface treatment of tungsten-carbide to enhance wear resistance. Additionally, the drum portion has an average roughness, or Ra value, of between 10 and 250 microns.
