A coupling device used for driving or in the drives of, agricultural implements or machinery, has a first universal joint (2) with a first outer yoke (3) a first inner yoke (4), a second universal joint (5) with a second outer yoke (6) and a second inner yoke (7). A connecting member (8) connects the first inner yoke (4) and the second inner yoke (7) to one another in a rotationally fast way. A first coupling element (12) is connected to the first outer yoke (3) in a rotationally fast way. A pressure spring (16) is axially supported against and pretensioned between a supporting element (15), which forms part of the connecting member (8), and the first coupling element (12). A longitudinal adjusting member enables an axial displacement of the first coupling element (12) relative to the supporting element (15).
