The device comprises mainly a first end (46) of a control lever (40) provided with a drive hole (45) that drives the driving part (16) of a blade (10) through a first contact area (41). The close contact between these two parts in this area is obtained using a play compensation plate (50) bearing on a side part (47) of the control lever (40), and fixed to the assembly using a nut (60) screwed onto the external pivot (11) of the blade (10).The device is used in turbo-machines.
