On Airbus, a double click on side stick takeover button is standard with us to disconnect the autopilot - Doing this brings up a master warning.
To disconnect the autothrust, you need to click either button on the thrust levers. Sitting here, I can't remember if this is one or two clicks - I just do it automatically.
