The present invention relates to a modular actuator system including at least two shaft elements arranged parallel to each other and extending in a first direction, at least two blade elements mounted on each shaft element in different horizontal levels substantially perpendicular to the first direction, with all blade elements mounted on one of the shaft elements being fixedly secured thereto, whereas at least one of the blade elements mounted on another shaft element can rotate around the axis of this other shaft element, and at least three SMA wires to connect the blade elements with each other and a fixed position, with power being supplied to one of the SMA wires leading to a rotation of all blade elements.
