An actuator device has at least one actuator element which at least in part is composed of a magnetically shape-shiftable material, and has a magnet unit which comprises at least one first magnetic element that is implemented as a coil unit and at least one second magnetic element that is implemented as a permanent magnet,
at least the first magnetic element and the second magnetic element are configured for interacting in at least one operating state so as to cause a local deformation of the actuator element in a partial region of the actuator element.
