Devices for capping vials useful in system and method for dispensing prescriptions

An apparatus for securing a closure on a cylindrical container, the apparatus comprising:

• a centering assembly having a main stage, the main stage including a receiving region for separately receiving a closure and a container, the main stage further comprising centering members that are configured to substantially center the closure and the container sequentially along a first axis generally normal to the stage;
• an elevator positioned such that a lifting member thereof is disposed over the main stage, the elevator including a capturing member that is configured to capture a closure, the elevator being configured to move between a lowered position, in which the elevator can capture the closure from the main stage, a raised position, in which a container can be received on the main stage below the captured closure, and an intermediate securing position, in which the closure is lowered to be adjacent an upper edge of the container;
• wherein the centering members comprise a plurality of clamps, each clamp being rotatably attached to the main stage for rotation about an axis that is substantially parallel to and radially outward from the first axis;
• wherein the main stage is configured to rotate about the first axis;
• and
• wherein the centering assembly includes a central sun gear that rotates with the main stage about the first axis, and wherein each of the clamps is connected to and rotatable with a respective clamp gear, each of the clamp gears engaging and being driven by the sun gear.
