1. An actuator apparatus, comprising:

  • a stator device;

    a cover device;

    a contact device including two lead wires; and

    an attenuation device;

    wherein;

    the stator device and the cover device are joined so that a hollow space is formed between the stator device and the cover device;

    the cover device has a first opening, through which the contact device is guided together with the lead wires into the hollow space, so that the contact device runs at least partially in the hollow space and at least partially in the cover device;

    a width of the first opening is larger than a combined width of the two lead wires;

    the hollow space has no other openings besides the first opening;

    the attenuation device is positioned in the first opening so that electromagnetic radiation, which is generated in the hollow space and travels through the first opening, is more highly attenuated by the attenuation device than the radiation would be attenuated without the presence of the attenuation device;

    a body of the attenuation device is formed of a material that is dimensioned such that, when the body is positioned in the first opening, the attenuation device attenuates at a frequency of the electromagnetic radiation generated in the hollow space; and

    the body of the attenuation device surrounds the contact device while mechanically sealing the hollow space by forming a seal around an inner surface of the first opening.
