    Abstract: Clutch (100) for a rotary shaft (10), said clutch (100) comprising an annular pressure chamber (110) with a sleeve surface (131 ) engaging a surface (11 ) to drivingly connected the shaft (10) to the clutch (100), further comprising a trigger device (140) and a channel system (150) activatable by said trigger device (140) upon a relative angular movement between the shaft (10) and the chamber (110) to release the shaft (10) from the housing (120). The invention is characterised in that the clutch (100) further comprises a control means (160), arranged to receive said fluid through the channel system (150) from the chamber (110), and comprising a pump (161 ) for pumping fluid to the chamber (110). The control means (160) is fixedly arranged to the housing (120), rotating with the shaft (10). The clutch (100) comprises a generator means (163), harvesting electric energy from the rotation of the shaft (10) and powering the control means (160).

    Abstract: Clutch (100) for a rotary shaft (10), said clutch comprising an annular pressure chamber (110) with a sleeve surface (131) engaging a surface (11) to drivingly connected the shaft to the clutch, further comprising a trigger device (140) and a channel system (150) activatable by said trigger device upon a relative angular movement between the shaft and the chamber to release the shaft from the housing. The trigger device comprises a cam wheel (141) having a constant first radius (Rl) across a first angular interval (All) and a second, smaller, radius (R2) across a second angular interval (AI2), the cam wheel being supported on an envelope surface (12) within the first angular interval and rotating in relation to the envelope surface when the shaft rotates in relation to the housing. When a contact point reaches the second angular interval, the cam wheel is displaced to activate said channel system.
