A hydrodynamic coupling apparatus ( 10 ) for transmitting torque between driving and driven elements includes an input shaft ( 14 ), a first end ( 16 ) of which is rotatably supported in a case ( 12 ) and a second end ( 18 ) of which is connectable to a torque generator ( 20 ). A hydrodynamic clutch ( 22 ) is connected to the first end ( 16 ) of the input shaft ( 14 ) and includes an impeller ( 34 ) and a turbine ( 36 ) enclosed in a clutch housing ( 24 ). The impeller ( 34 ) is fixed to the first end ( 16 ) of the input shaft ( 14 ), and the turbine ( 36 ) is rotatably supported adjacent the impeller ( 34 ). Both the impeller ( 34 ) and the turbine ( 36 ) are immersed in magnetorheological fluid ( 30 ). An electromagnetic field generator ( 32 ) is supported adjacent the clutch housing ( 24 ) and is operable to generate a magnetic field in the magnetorheological fluid ( 30 ). The field generator is adjustable to adjust the density of the magnetic field flux and, consequently, the amount of torque transferred from the impeller ( 34 ) to the turbine ( 36 ).
