An actuating device includes a first actuating device mounted to a second actuating device. Each of the first and second actuating devices includes a base link, a first link, a second link, a translating link, a shaft, and a drive. The base link includes a first joint, a second joint, and a base plate extending between them. The first link is mounted for rotation to the first joint, and the second link is mounted for rotation to the second joint. The translating link includes a third joint, a fourth joint, and a translating plate extending between them. The drive includes an arc surface and is mounted to the translating link such that, when operating the actuating device, a position of the arc surface is fixed relative to the translating plate. The shaft is mounted to the arc surface to cause translation of the translating link as the shaft rotates.
