 ### AAS/AID to WoT TD
 
-The file `counterHTTP.json` describes the counter sample in AAS/AID format for http binding. The `AssetInterfaceDescriptionUtil` utility class allows to transform the AID format to a valid WoT TD format which in the end can be properly consumed by node-wot.
+The file `counterHTTP.json` describes the counter sample in AAS/AID format for http binding. The `AssetInterfacesDescription` utility class allows to transform the AID format to a valid WoT TD format which in the end can be properly consumed by node-wot.
 
 The example `aid-to-td.js` tries to transform an AID submodel (from an AAS file) into a regular WoT TD.
 Note: Besides converting the AID submodel it is also possible to convert a full AAS file (see `transformTD2AAS(...)`).
