1. An apparatus for converting linear motion to rotary motion about a first axis, comprising:
a plurality of assemblies, each assembly including:
a plate having at least one connection point extending outwards and a channel through the center;
a wobbler having an end that extends along the first axis and at least one cylindrical body having a second axis that is parallel to the first axis and offset from the first axis;
wherein the plate is rotatably connected to the cylindrical body and configured to rotate about the second axis; and
a flexure having a first end, a second end, a length extending in a direction perpendicular to the second axis, a width extending parallel to the second axis, and a thickness;
wherein the first end of the flexure is connected to a first connection point of the at least one connection point of the plate, and the second end of the flexure is configured to move in a direction perpendicular to the first axis;
wherein each second axis of the plurality of assemblies has its own respective offset from the first axis,
wherein the flexures of the plurality of assemblies are spaced apart and in parallel to one another, and extend in substantially the same direction perpendicular to the respective second axis, and
wherein the flexures of the plurality of assemblies include at least a first flexure and a second flexure adjacent to the first flexure, the second end of the first flexure being connected to a piston rod, the second end of the second flexure being connected to a cylinder body, and the piston rod being configured to drive through the cylinder body.
