An actuator apparatus is described as having a stator device, a cover device, a contact device and an attenuation device. The stator device and the cover device are joined in such a manner so that a hollow space is formed between the stator device and the cover device. The cover device has an opening, through which the contact device is guided 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. The attenuation device is positioned in the opening in such a manner so that a high-frequency electromagnetic radiation that travels through the opening is more highly attenuated by the attenuation device than the radiation would be attenuated without the presence of the attenuation device.
