A gyroscopic stabiliser for stabilising motion of an object, the gyroscopic stabiliser comprising: a support for attaching to the object whose motion is to be stabilised; a gimbal rotatably supported by the support to be rotatable around a first axis relative to the support; a flywheel rotatably supported by the gimbal to be rotatable around a second axis relative to the gimbal, the second axis being orthogonal to the first axis; and a rotary damper for damping rotation of the gimbal around the first axis relative to the support; wherein the rotary damper comprises: a chamber containing a damping fluid; a vane that is rotatable within the chamber and that is coupled to the gimbal; and a flow passage allowing flow of the damping fluid from the chamber on one side of the vane to the chamber on the other side of the vane when the vane is rotated, wherein the flow passage comprises a flow valve configured to provide substantially the same flow rate of fluid through the flow passage for different torques applied to rotate the vane.
