1. A rotary tablet compression machine comprising a die table and a feeder platform,
wherein the feeder platform further comprises adjustable supports to level the feeder platform to be parallel to the die table;
wherein mounted on the die table is a leveling device;
wherein the leveling device is used for leveling the feeder platform to be parallel to the die table;
wherein the leveling device comprises:
a top plate, a bottom plate, and at least three distance sensors;
wherein the top plate and the bottom plate are attached;
wherein the top plate and the bottom plate are rigid;
wherein the top plate has a top plate surface and a feeder platform surface;
wherein the bottom plate has a die table engaging surface;
wherein the bottom plate is engaged with the die table;
wherein the feeder platform surface is offset from the die table engaging surface, creating an offset gap between the feeder platform and the feeder platform surface; and
wherein the at least three distance sensors are mounted in a non-linear fashion on the feeder platform surface;
wherein the at least three distance sensors are linearly adjustable;
wherein the die table engaging surface and the feeder platform surface are essentially flat and are parallel to the each other;
wherein the die table engaging surface and the feeder platform surface are sized such that when mounted on the rotary tablet compression machine, the die table engaging surface is parallel to the die table and the feeder platform surface is parallel to the feeder platform in order to level the feeder platform to be parallel to the die table of the rotary tablet compression machine;
wherein the bottom plate has a turret notch configured to engage with a turret on the tablet compression machine; and
wherein the top plate has a clearance cutout configured to engage with the die table.
