Abstract
A motor vehicle power take off system for a motor vehicle engine includes a viscous coupling. The input rotor of the viscous coupling is provided with a variable geometry impeller section which allows direct control over the proportion of input torque on the input shaft transferred to the viscous fluid and thereby to an output shaft. Both passive and active control schemes are proposed.
