A hydrodynamic coupling device includes a hydrodynamic circuit having at least an impeller wheel and a turbine wheel and a lockup clutch having an axially movable piston and a torsional vibration damper. The torsional vibration damper has a drive-side transmission element and a driven-side transmission element which is rotatable relative to the latter, each of which is provided with driving means for elastic elements of the torsional vibration damper. A first driving device is provided at a radial outer area of the turbine wheel. For an arrangement of the elastic elements substantially radially outside of the impeller wheel, the first driving device extends beyond this impeller wheel. The second driving device has at least one area radially outside of the elastic elements which receives a friction facing or which serves as a friction surface for the friction facing.
