A propeller propulsion assembly for an aircraft has a transmission shaft (2), which extends along an axis (3) and ends with an attachment portion (4) on which a propeller is mounted; the shaft (2) is driven by a transmission device (29) having a first body (15) coaxial and rotating relative to the shaft (2), a second body (6) coaxial and angularly fixed relative to the shaft (2) and an elastic device (8) exerting a thrust on the second body (6) to arrange said bodies in a reference position and compensate relative angular movements around said reference position. The assembly (1) further comprises a clutch (5) which is normally engaged to transmit drive torque to the first body (15) and is configured so as to automatically disengage when the resulting torque becomes a braking torque and exceeds a given threshold.
