A gyroscopic stabiliser for stabilising motion of an object, for example rolling or pitching motion of a marine vessel. The gyroscopic stabiliser includes a rotary damper for damping precession of the gyroscopic stabiliser, wherein the rotary damper includes a constant flow valve that provides a constant flow of damping fluid in the rotary damper for different torques applied to the vane of the rotary damper. The constant flow valve comprises a fixed orifice and a variable orifice in series in the flow passage, wherein a change in a pressure differential across the fixed orifice causes a change in a size of the variable orifice. A biasing element may apply a biasing force to a displaceable member which changes the size of the variable orifice. The fixed orifice may be located upstream of the variable orifice.
