1. A valve control device for controlling the opening and closing of a valve, comprising a first control arm and a second control arm, wherein the first control arm is arranged to rotate around a first axis at a first end, wherein the second control arm is arranged to rotate around a second axis at a first end, wherein the first axis is perpendicular to the second axis, wherein a second end of the first control arm is provided with a fork having an upper bearing surface and a lower bearing surface, wherein a second end of the second control arm is provided with a rotatable member, wherein the rotatable member is rotatable around a centre axis, and wherein the rotatable member is attached to the second control arm-on a mounting surface, wherein a plane of the mounting surface is angled with respect to a plane of the second control arm that is perpendicular to the second rotational axis such that the centre axis of the rotatable member is parallel to the upper bearing surface and the lower bearing surface of the fork during movement of the first control arm relative to the second control arm.
