Django model string representation

I know that a model object string representation can be achieved by adding

class Company(models.Model):
    name = models.CharField()
    email = models.EmailField(unique=True)

    def __str__(self):
        return self.name

But this is the representation of an object of Company but not the model class itself. Meaning if I create an object

obj = Company(name='string_repr', email='example@example.com')

print(obj) would result in 'string_repr' which is as expected since Im getting the string representation of the object, not the class/ model. However I noticed that during a CreateView form validation in case if there already is an object of the model with the same email Django returns an error message that there already is a Company with such an email (picture is not in English but the underlined section is the only relevant part).

I suppose the error message is taking the class name and inputting it in the message, but is there a way how to alter the string representation of the model (class) name? Its needed for translation purposes. I guess I could just rename the class names to local language but that doesn't seem right.
