Where does it say /ʌ/on this site?
Note that when you say "this site", you are referring to usingenglish.com!

Take a look at the link below. It has both American and British English pronunciations (click on the speaker icons), as well as the phonetic characters for "cough."

Note also that "cuff" (which is pronounced /kʌf/) is another word in English.
