A filling-controlled hydrodynamic coupling comprises a pump wheel and a turbine wheel which delimit a working chamber and which can be mechanically coupled to one another by means of a hydraulic fluid; a direct circuit, which connects a hydraulic outlet to a hydraulic inlet of the working chamber; a pump device, which is arranged hydraulically between a fluid source and the direct circuit; and a lubrication line, which leads from the pump device to a lubrication point of the coupling. Here, the pump device is designed to convey fluid in a first conveying direction from the fluid source into the working chamber and into the lubrication line or in a second conveying direction from the working chamber to the fluid source.
