Abstract: An electromechanical actuator comprises a housing, a torque support (21) and a module for filtering vibrations (33). The torque support (21) comprises a shaft (35) extending along an axis of rotation (X) of the actuator. The module (33) is arranged inside the housing and comprises a transmission element (36), a stop (38) and first and second viscoelastic elements (39, 40). The transmission element (36) is mounted around the shaft (35) and is attached to the housing. The stop (38) is connected to the shaft (35). The first viscoelastic element (39) is arranged between the torque support (21) and a first end (36a) of the transmission element (36). The second viscoelastic element (40) is arranged between a second end (36b) of the transmission element (36) and the stop (38).
