## Abstract

An aircraft high-lift device comprising a kinematic chain connected to flaps, the kinematic chain comprising a plurality of shafts connected by coupling systems. This high-lift device comprises at least one differentiated coupling system different from the non-differentiated coupling systems, the differentiated coupling system being configured to be coupled to an adapter and comprising at least one poka-yoke feature. Another subject of the disclosure is an aircraft which comprises at least one high-lift device.

## Claims

### Claim 1

An aircraft high-lift device, comprising:
a kinematic chain connected to flaps, the kinematic chain comprising a plurality of shafts connected to one another by non-differentiated coupling systems; and
at least one differentiated coupling system that differs from the non-differentiated coupling systems,
wherein the differentiated coupling system is configured to be coupled to an adapter and comprises at least one poka-yoke feature, and
wherein the adapter is configured to connect the differentiated coupling system to an external drive.

### Claim 2 (depends on 1)

The high-lift device according to claim 1, wherein the poka-yoke feature comprises shapes which collaborate between the differentiated coupling system and the adapter.

### Claim 3 (depends on 2)

The high-lift device according to claim 2, wherein the differentiated coupling system comprises a recessed shape configured to accept a projecting shape provided on the adapter.

### Claim 4 (depends on 1)

The high-lift device according to claim 1, wherein the poka-yoke feature comprises a transmission cross section for the differentiated coupling system that differs from those of the non-differentiated coupling systems.

### Claim 5 (depends on 4)

The high-lift device according to claim 4, wherein the transmission cross section of the differentiated coupling system is a recessed shape with a cross section that differs from those of the non-differentiated coupling systems.

### Claim 6 (depends on 5)

The high-lift device according to claim 5, wherein the recessed shape of the differentiated coupling system has a cross section greater than a cross section of the recessed shapes of the non-differentiated coupling systems.

### Claim 7 (depends on 1)

The high-lift device according to claim 1, wherein the poka-yoke feature comprises a plurality of connecting elements for the differentiated coupling system that differs from those of the non-differentiated coupling systems.

### Claim 8 (depends on 1)

The high-lift device according to claim 1, wherein the poka-yoke feature comprises passage-orifices for the differentiated coupling system, at least one of which is positioned differently with respect to passage-orifices of the non-differentiated coupling systems.

### Claim 9 (depends on 1)

The high-lift device according to claim 1, comprising a plurality of differentiated coupling systems, each differentiated coupling system comprising at least one poka-yoke feature that differs from other differentiated coupling systems.

### Claim 10 (depends on 1)

An aircraft comprising at least one high-lift device according to claim 1.

### Claim 11 (depends on 2)

The high-lift device according to claim 2, wherein the non-differentiated coupling systems comprise identical recessed shapes that differ from the recessed shape of the differentiated coupling system.

### Claim 12 (depends on 1)

The high-lift device according to claim 1, wherein the external drive is configured to operate the flaps while one or more shaft of the kinematic chain is removed.
