Systems and techniques may generally be used for a fence configurable between a static state and a dynamic state. A system may include a plurality of structural support posts and at least one panel disposed between two of the posts. A rotational coupling assembly may pivotally connect the panel to the two posts to define a pivot axis. A releasable locking mechanism may be configured to selectively secure the panel in a fixed, non-rotational orientation in the static state, and may be further configured to permit 360 degree rotation of the panel about the pivot axis in the dynamic state in response to aerodynamic loading. Implementations may include upper- or lower-edge placement of the rotational coupling assembly, manual or electromagnetic locking, and panel cartridges adapted for serviceability and varied surface constructions, while maintaining the selectable transition between privacy / security operation and wind-responsive operation.

In order to improve the manual operation of an actuator (1), a novel clutch (4, 6) is proposed, which has at least one movable protrusion (12) that can be moved axially along the coupling axis (11) of the clutch (4, 6) relative to the element (8) that carries the protrusion (12). This design has the advantage that the clutch (4, 6) can be engaged in all cases even if the protrusion (12) is not yet in the correct rotational coupling position (18), since the protrusion (12) can always be transferred into the coupling position (18) by a rotational movement (24, 25).
