The invention concerns a propulsion device (1) comprising a torque generator (2) driving an output shaft (3) via a power gearbox (4), the output shaft (3) being rotatably coupled to a thruster (5), said power gearbox (4) being fixed on a frame (7) by means of suspension means (8, 14, 15), said suspension means including hydraulic torque recovery means comprising at least a first hydraulic system (15) and a second hydraulic system (15) spaced from each other, each hydraulic system (15) having a pressure chamber whose volume varies according to the position of the housing (9) of the power gearbox (4) relative to the frame (7), the pressure chambers of the hydraulic systems (15) being connected by a capillary so that a hydraulic fluid is able to flow from one pressure chamber to another via the capillary.
