An electromechanical actuating assembly can have a redundant design with a first electric motor providing actuator-moving power via a first drive train and a second electric motor providing actuator-moving power via a second drive train. A first decoupling train can transmit decoupling power to decouple the first drive train from the actuator and a second decoupling train for transmit decoupling power to decouple the second drive train from the actuator. The assembly is operable in a fault-tolerant mode wherein actuator-moving power is transferred only through one drive train and the other drive train is decoupled from the actuator.
