115 and the clutch bell 105 in the proximity of the axis of rotation 110 the axial contact area 140 of the support element 115 contacts the clutch bell 105 at an axial contact area 305 this contact prevents any further motion of the support element 115 towards the right resulting in a gap 220 forming in fig2 as long as the support element 115 is free from tension i e it is supported without any stress towards the right in the area of the securing point 135 the radial contact area 145 of the support element 115 contacts a radial contact area 310 of the clutch bell 105 here the contact areas 145 and 310 are circumferential about the axis of rotation 110 so that the release device 100 is centered about the axis of rotation 110 with regards to the clutch bell 105 fig4 shows another detail of the release device 100 of fig1 in the area c indicated there the detail shows a hydraulic connector element 150 of the release device 100 the hydraulic adapter 150 is allocated to one of the hydraulic actuators 120 125 a first channel 405 extends within the support elements 115 in a direction parallel in reference to the axis of rotation 110 additional channels within the support element 115 not shown in their entirety connect the first channel 405 to a cylinder 410 of one of the actuators 120 125 the cylinders 410 are formed like rings and.
