## Abstract

The attachment device includes a base plate which is magnetically engaged to an end of a rotating shaft, the plate having a centered collar which is coaxial with the axis of the shaft and is configured to engage a rotatable spindle of a sensor mount to the shaft, with the spindle being rotated by rotation of the shaft.

## Claims

### Claim 1

An attachment device for engaging a sensor via a universal rotational sensor mount including a rotatable spindle, to an end of a rotating shaft, the device consisting essentially of a base plate including at least one magnet therein and a centered collar extending outwardly of the base plate in a direction opposite that of the at least one magnet, the collar having a threaded bore therein for threadedly engaging the spindle of the universal rotational sensor mount, with the at least one magnet in the base plate engaging the device to the end of the rotating shaft.

### Claim 2 (depends on 1)

The device of claim 1 wherein the device is unitary.

### Claim 3 (depends on 1)

The device of claim 1 wherein the base plate and collar are separate structures.

### Claim 4 (depends on 1)

The device of claim 1 wherein the base plate has a hollowed out face.

### Claim 5 (depends on 4)

The device of claim 4 wherein the at—least one magnet is seated within the hollowed out face.

### Claim 6 (depends on 5)

The device of claim 5 wherein the at least one magnet is engaged within the face by an epoxy.

### Claim 7 (depends on 3)

The device of claim 3 wherein the base plate has a center orifice therein.

### Claim 8 (depends on 7)

The device of claim 7 wherein the collar has an inner end which extends through the orifice in the base plate and mechanically engages the base plate.

### Claim 9 (depends on 7)

The device of claim 7 wherein the collar has a secondary threaded bore which aligns with the center orifice in the base plate, the collar being fixed to the base plate with a threaded connector.

### Claim 10 (depends on 9)

The device of claim 9 wherein the threaded connector is a bolt.
