Adaptors for positioning a force gauge relative to a control interface in a flight simulator or aircraft are disclosed where the control interface is moveable in at least one of a back-and-forth direction and a side-to-side direction. In some embodiments the adaptor comprises a housing positionable adjacent the control interface where the housing comprises a first surface configured to snugly receive a predetermined surface of the control interface and a second surface comprising a first housing connector configured for connection to the gauge connector such that pressure is exertable on the control interface by the force gauge in a first direction of measurement aligned with one of the back-and-forth direction and the side-to-side direction.
