1. An actuator for a fuel tank overpressure relief valve of an aircraft, the fuel tank overpressure relief valve being positioned at a first end of a cavity in the aircraft and an opening in a skin of the aircraft being positioned at a second end of the cavity, the opening defining a first surface area and an opening peripheral edge, the actuator comprising:
a stem comprising a first end connected to the fuel tank overpressure relief valve and a second end in proximity to the opening in the skin of the aircraft; and
an exterior surface located at the second end of the stem that defines:
a second surface area that is less than the first surface area of the opening; and
a device peripheral edge comprising:
i) at least one first section having an edge profile complimentary to at least a portion of the opening peripheral edge; and
ii) at least one second section having an edge profile indented in relation to the at least one first section such that when the noise attenuating device is secured within the opening, at least one gap is formed between the device peripheral edge and the opening peripheral edge.
