Abstract
A valve unit with a valve having a valve shaft with a rotational axis. The valve unit including an actuator having an actuator shaft with a rotational axis. The valve unit includes a mechanical coupler for rotational coupling of the actuator shaft and the valve shaft. The mechanical coupler includes a rotational axis coinciding with the rotational axis of the actuator shaft and the rotational axis of the valve shaft. The valve unit includes a first rotational member coupled to the actuator shaft and a second rotational member coupled to the valve shaft. The valve unit includes a bridge element. The first and the second rotational members include slots for receiving engagement pins of the bridge element.
