A device for coupling an input shaft and an output shaft of an automobile is provided. The device preferably includes a rolling element, a holding element adapted to contain annular movement of the rolling element and allow axial movement of the rolling element, an annular cam adapted to cause axial movement of the rolling element upon relative rotational movement of the annular cam and the holding element, a pressure chamber, and a piston adapted to increase pressure in the pressure chamber upon axial movement of the rolling element and to resist axial movement of the rolling element upon the presence of sufficient pressure in the pressure chamber.
