The invention relates to a device (10) for damping torsion in a motor vehicle temporary coupling system, the device (10) being equipped with: - first damping means which comprise at least two circumferentially- acting elastic members and a radial phase washer (38, 38A) for phasing the elastic members; - and second damping means which comprise a pendular flyweight (54) mounted such that it can oscillate on the first phase washer (38, 38A) via an axial guide pin (58); characterized in that the pendular flyweight (54) is interposed axially between the first phase washer (38, 38A) and a second radial support plate (38B, 38D), which is fixed with respect to the phase washer (38, 38A).
