Abstract
A torsion damping device, for example for a motor vehicle fluid transmission, includes a first pair of guide rings, a second pair of guide rings fixed to a torque input element, a first hub fixed to a second pair of guide rings, a second hub, a first series of springs coupling the first pair of guide rings to the first hub, a second series of springs coupling the second pair of guide rings to the second hub, and an abutment member for limiting the relative angular displacement between the first pair of guide rings and the first hub. The first pair of guide rings is fastened to the torque input element by fastening members. These fastening members and the abutment member are both located radially inwardly of one of the two series of springs, and radially outwardly of the other series.
