The invention concerns a vibration damping device (2). This includes at leas t two elements - a primary element (3.1) and a secondary element (3.2) -, which ar e limited in movement in relation to each other. The primary element (3.1) and the secondary element (3.2) can be coupled together using a spring coupling. The means to implemen t spring coupling include at least one spring device (4.1, 4.N). Based on the invention, there is at least one adjustable clutch device (15, 15'), including at least two element s (16, 17; 16', 17') rubbing against each other, which bring primary and secondary elements (3.1,3.2) into friction contact. In addition, there is a power generator or force producing device (39) to produce a controllable friction contact for the elements rubbing against eac h other (16, 17; 16', 17').
