Abstract
A viscous coupling having outer plates which are provided with index recesses which serve to assemble the outer plates in a specific way relative to each other, depending on the respective application. If the outer plates have to be assembled in the housing with the apertures being aligned inphase relative to each other, the torque transmitting capacity of the coupling is lower than in those cases where the slots are circumferentially offset relative to each other in the housing, thereby forming a kind of labyrinth, in which case the viscous coupling achieves a 100% torque transmission because it may be transferred into the hump mode.
