The invention relates to a hydrodynamic coupling comprising a primary blade wheel and a secondary blade wheel. The primary wheel and the secondary wheel together form a working chamber that can be filled with a working medium, and are mounted in such a way that they can rotate in relation to each other. A bearing is inserted, at least indirectly, between the primary wheel and the secondary wheel, and absorbs the radial forces and/or axial forces acting between the blade wheels. The inventive hydrodynamic coupling is characterised in that the bearing is embodied as a plain bearing, a film of bearing fluid subjected to hydrostatic pressure being formed between the bearing components moving in relation to each other, during the operation of the hydrodynamic coupling, and the pressure of the bearing fluid is dependent on the pressure of the working medium accumulated in the working chamber.
