A rotary device includes a rotatable member and a limiting member. The rotatable member includes a positioning mechanism, the positioning mechanism includes a stopping member and a positioning member. When the rotatable member rotates along a first rotation direction to make the limiting member abut against the positioning member, the positioning member is pushed by the limiting member to move away from the stopping portion and rotate relative to the stopping member, so that the positioning member to passes through the limiting member; when the rotatable member rotates along a second rotation direction opposite to the first rotation direction to make the limiting member abut against the positioning member, the positioning member is pushed by the limiting member to move close to the stopping portion, so that the positioning member is stopped between the limiting member and the stopping portion, to position the rotatable member.

An intermittent drive system includes a rotatable output component, a rotating input component with a driving engagement element, a synchronizing ring and a decoupling ring. The synchronizing ring is coupled to the output element to rotate therewith. The synchronizing ring has a driven engagement element configured to selectively engage with the driving engagement element. The synchronizing ring has an alignment feature configured to rotationally align the driving engagement element with the driven engagement element and has a decoupling feature configured to selectively disengage the driving engagement element from the driven engagement element. The decoupling ring is selectively coupled to the input component and has a decoupling feature configured to selectively engage the decoupling feature of the synchronizing ring. The driving engagement element engages the driven engagement element only when both the alignment feature is rotationally oriented to align the driving engagement element with the driven engagement element and the decoupling features are rotationally oriented to allow the driving engagement element to engage the driven engagement element.

An adjustment drive that includes an electric motor, a transmission having a self-locking transmission stage, an output, and a safety clutch having a free travel. The safety clutch is operable to separate, in an event of an excessive external torque introduced via the output, the self-locking transmission stage from the external torque. The adjustment drive also includes at least one compressible damping element arranged in the free travel to enable haptics of an external movement demand introduced via the output.
